What is LiDAR and what is it used for?

by Alicia Turner Professional SEO

While LiDAR (Light Detection and Ranging) is not a wholly new technology, it is still necessary to understand what exactly it is so as to make even more extensive use thereof in the future.

Essentially, LiDAR operates by pulsing a laser onto a specific point, which laser allows surveyors to make allowances for dense objects like trees and/or built structures as part of their measurements. LiDAR also makes it possible to better determine the depth and density of an object – for example, laser readings can indicate changes in rock density or ocean depth. As such, LiDAR can provide highly accurate readings, which are necessary to ensure safety when undertaking any construction or excavation activities.


UAV LiDAR, otherwise known as LiDAR that operates via the use of a drone (Unmanned Aerial Vehicle), is especially beneficial for covering larger distances. This approach to surveying, rather than using manned vehicles like helicopters, tends to work out cheaper, as it is more cost-effective to operate and transport a drone than it is to fly a manned vehicle. When using UAV LiDAR, the drone is flown over the area to collect LiDAR point data. This data is then transmitted and stored in specialized software that can convert the data to visual representations (i.e., maps).

While LiDAR is most commonly known and used in the fields of construction and archaeology, it’s uses extend much further, including traffic congestion mapping to better plan roads; crop mapping to determine where to plant different crops so as to gain better yields; and pollution modelling, which can help to determine areas where there is significant pollution build-up and, thereby, assist stakeholders in finding ways to reduce pollution in these areas.

It is likely that as LiDAR technology continues to improve, its uses may become even more varied.
